Crabapple trees are in abundance in Calgary, but true apple trees tend to be less common. Both are in the same genus and are very closely related and similar. What differentiates the two is the size of the fruit. A crabapple has fruit that is 2” (5cm) or less in diameter.
There are several types of apple trees that can be very successful in Calgary including Norland, Prairie Sensation, Goodland, Alberta Gold, and Alberta Red. Carlos Queen, Annas Gold, and Norkent may be less popular but are also available from specialty fruit tree suppliers like DNA Gardens.
Most apple trees grown in Calgary will reach 15 to 20 feet (4.5 to 6 metres) in height and width, but in some cases can be available as dwarf selections. These are grafted onto dwarf root stock and will reach only half of this size – a great option for a smaller garden. In the CKE Community Garden, we have a TreasuRed, planted a few years ago. This is columnar in shape, staying fairly narrow. It will reach approximately 15 feet (4.5m) in height but only 3 to 4 feet (1 to 1.5m) in width. It’s also possible to plant a combination apple tree, which can have several different types of apples grafted onto a single trunk. Apples can be grown for eating, cooking, and storing so select a variety that suits your needs.
When choosing a location in your yard, make sure you have space to accommodate the tree’s mature size. Apple trees need full sun (minimum six hours per day), well-draining soil and will benefit from a layer of mulch around the base to help with winter hardiness. All apple trees need to be cross-pollinated by an apple of a different variety, or even by a crabapple. The two plants do not need to be located next to each other. They could be in the same yard, or even in a neighbour’s yard several houses away.
Apples can be ready for picking as early as late July all the way through September depending on the cultivar so take a look and see what apples might be ripening in your area. You can check out TreasuRed apple tree and other fruit trees and shrubs in the CKE Community Garden.
